#424002.
Refactor init_path_from_argv0() and rename to copy_absolute(); add
absolutize() which does the same in-place.
Clean up whitespace (leading tabs -> spaces, delete trailing
spaces/tabs).
depending on the cycle detector code in the library implementation.
This is a *slightly* different patch than SF patch #417795, but takes
the same approach. (This version avoids calling the __len__() method of
the dict in the remove() functions.)
This closes SF patch #417795.
fallback for objects that are neither supported by our dispatch table
nor have a __copy__ or __deepcopy__ method.
Changes to _reduce() in copy_reg.py to support reducing objects that
don't have a __dict__ -- copy.copy(complex()) now invokes _reduce().
Add tests for copy.copy() and copy.deepcopy() to test_regrtest.py.
For the real document element, make sure the prolog is migrated into
the document element so it isn't left stranded.
Make fixup_trailing_whitespace() whitespace do what was really intended.
Add the *desc environments used in the C API manual to the list of
things that can exist at the paragraph level so they don't get wrapped
in <para>...</para>.
whether or not a link will be generated will depend on the link database.
Add a couple of explanatory comments for one of the stranger constructs
(giving input an empty name).
used with text as was done here. Fixed so that the typeset version wraps
the warning text and the HTML version does not create images of the warning
text.
getting displayed, due to a special case here whose purpose I didn't
understand. So just disabled the doc suppression here.
Another special case here skips the docs when picking apart a method
and finding that the im_func is also in the class __dict__ under
the same name. That one I understood. It has a curious consequence,
though, wrt inherited properties: a static class copies inherited stuff
into the inheriting class's dict, and that affects whether or not this
special case triggers. The upshoot is that pydoc doesn't show the
function docstrings of getter/setter/deleter functions of inherited
properties in the property section when the class is static, but does
when the class is dynamic (bring up Lib/test/pydocfodder.py under
GUI pydoc to see this).
Add raise_exception() to the _testcapi module. It isn't a test, but
the C API exists only to support test_exceptions. raise_exception()
takes two arguments -- an exception class and an integer specifying
how many arguments it should be called with.
test_exceptions uses BadException() to test the interpreter's behavior
when there is a problem instantiating the exception. test_capi1()
calls it with too many arguments. test_capi2() causes an exception to
be raised in the Python code of the constructor.
If a new exception occurs while an exception instance is being
created, try harder to make sure there is a traceback. If the
original exception had a traceback associated with it and the new
exception does not, keep the old exception.
Of course, callers to PyErr_NormalizeException() must still be
prepared to have tb set to NULL.
XXX This isn't an ideal solution, but it's better than no traceback at
all. It occurs if, for example, the exception occurs when the call to
the constructor fails before any Python code is executed. Guido
suggests that it there is Python code that was about to be executed
-- but wasn't, say, because it was called with the wrong number of
arguments -- then we should point at the first line of the code object
anyway.
It's possible for PyErr_NormalizeException() to set the traceback
pointer to NULL. I'm not sure how to provoke this directly from
Python, although it may be possible. The error occurs when an
exception is set using PyErr_SetObject() and another exception occurs
while PyErr_NormalizeException() is creating the exception instance.
XXX As a result of this change, it's possible for an exception to
occur but sys.last_traceback to be left undefined. Not sure if this
is a problem.
In both the HTML and typeset versions of the documentation, add a colon
after the name of a mail header so that it is more easily distinguished
from other text.
Clarify the \mimetype description; it can be used to refer to a part of a
MIME type name, so \mimetype{text} or \mimetype{plain} can be used, not
just \mimetype{text/plain}.
